The apparatus has a shear rotor (60) and a stator (70) for mixing the liquid (L) and material (P) and an impeller (50) for pumping the liquid (L) and material from the inlet (201), via an annular clearance (71) between the shear rotor (60) and the stator (70) and to the outlet (202). The apparatus has a return conduit (413) configured to return to the inlet (201) a part (M2) of the liquid (L) and material (P) pumped via the annular clearance (71) and openings (72) in the stator (70).
